Instead, we need to use '$large' and '$small' that are not local and defined just before setting the trap.

2021-08-26selftests/net: allow GRO coalesce test on vethPaolo Abeni
This change extends the existing GRO coalesce test to allow running on top of a veth pair, so that no H/W dep is required to run them. By default gro.sh will use the veth backend, and will try to use exiting H/W in loopback mode if a specific device name is provided with the '-i' command line option. No functional change is intended for the loopback-based tests, just move all the relevant initialization/cleanup code into the related script. Introduces a new initialization helper script for the veth backend, and plugs the correct helper script according to the provided command line. Additionally, enable veth-based tests by default. v1 -> v2: - drop unused code in setup_veth_ns() - Willem Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

2021-08-24selftests/net: Use kselftest skip code for skipped testsPo-Hsu Lin
There are several test cases in the net directory are still using exit 0 or exit 1 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in net directory: grep -r "exit [01]" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

2021-08-17selftests: net: improved IOAM testsJustin Iurman
As previously discussed with David Ahern, here is a refactored and improved version of the IOAM self-test. It is now more complete and more robust. Now, all tests are divided into three categories: OUTPUT (evaluates the IOAM processing by the sender), INPUT (evaluates the IOAM processing by the receiver) and GLOBAL (evaluates wider use cases that do not fall into the other two categories). Both OUTPUT and INPUT tests only use a two-node topology (alpha and beta), while GLOBAL tests use the entire three-node topology (alpha, beta, gamma). Each test is documented inside its own handler in the (bash) script. Signed-off-by: Justin Iurman <justin.iurman@uliege.be> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-08-05selftests/net: GRO coalesce testCoco Li
Implement a GRO testsuite that expects Linux kernel GRO behavior. All tests pass with the kernel software GRO stack. Run against a device with hardware GRO to verify that it matches the software stack. gro.c generates packets and sends them out through a packet socket. The receiver in gro.c (run separately) receives the packets on a packet socket, filters them by destination ports using BPF and checks the packet geometry to see whether GRO was applied. gro.sh provides a wrapper to run the gro.c in NIC loopback mode. It is not included in continuous testing because it modifies network configuration around a physical NIC: gro.sh sets the NIC in loopback mode, creates macvlan devices on the physical device in separate namespaces, and sends traffic generated by gro.c between the two namespaces to observe coalescing behavior. GRO coalescing is time sensitive. Some tests may prove flaky on some hardware. Note that this test suite tests for software GRO unless hardware GRO is enabled (ethtool -K $DEV rx-gro-hw on). To test, run ./gro.sh. The wrapper will output success or failed test names, and generate log.txt and stderr. Sample log.txt result: ... pure data packet of same size: Test succeeded large data packets followed by a smaller one: Test succeeded small data packets followed by a larger one: Test succeeded ... Sample stderr result: ... carrier ready running test ipv4 data Expected {200 }, Total 1 packets Received {200 }, Total 1 packets. ...

2021-07-21selftests: net: Test for the IOAM insertion with IPv6Justin Iurman
This test evaluates the IOAM insertion for IPv6 by checking the IOAM data integrity on the receiver. The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between) and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only, which means not on the reverse path. When Gamma is the destination, Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM data integrity is checked on Gamma, by comparing with the pre-defined IOAM configuration (see below). +-------------------+ +-------------------+ | | | | | alpha netns | | gamma netns | | | | | | +-------------+ | | +-------------+ | | | veth0 | | | | veth0 | | | | db01::2/64 | | | | db02::2/64 | | | +-------------+ | | +-------------+ | | . | | . | +-------------------+ +-------------------+ . . . . . . +----------------------------------------------------+ | . . | | +-------------+ +-------------+ | | | veth0 | | veth1 | | | | db01::1/64 | ................ | db02::1/64 | | | +-------------+ +-------------+ | | | | beta netns | | | +--------------------------+-------------------------+ ~~~~~~~~~~~~~~~~~~~~~~ | IOAM configuration | ~~~~~~~~~~~~~~~~~~~~~~ Alpha +-----------------------------------------------------------+ | Type | Value | +-----------------------------------------------------------+ | Node ID | 1 | +-----------------------------------------------------------+ | Node Wide ID | 11111111 | +-----------------------------------------------------------+ | Ingress ID | 0xffff (default value) | +-----------------------------------------------------------+ | Ingress Wide ID | 0xffffffff (default value) | +-----------------------------------------------------------+ | Egress ID | 101 | +-----------------------------------------------------------+ | Egress Wide ID | 101101 | +-----------------------------------------------------------+ | Namespace Data | 0xdeadbee0 | +-----------------------------------------------------------+ | Namespace Wide Data | 0xcafec0caf00dc0de | +-----------------------------------------------------------+ | Schema ID | 777 | +-----------------------------------------------------------+ | Schema Data | something that will be 4n-aligned | +-----------------------------------------------------------+ Note: When Gamma is the destination, Alpha adds an IOAM Pre-allocated Trace option inside a Hop-by-hop, where 164 bytes are pre-allocated for the trace, with 123 as the IOAM-Namespace and with 0xfff00200 as the trace type (= all available options at this time). As a result, and based on IOAM configurations here, only both Alpha and Beta should be capable of inserting their IOAM data while Gamma won't have enough space and will set the overflow bit.

Without this modification, we were often displaying this error messages: FAIL: Could not even run loopback test But $ret could have been set to a non 0 value in many different cases: - net.mptcp.enabled=0 is not working as expected - setsockopt(..., TCP_ULP, "mptcp", ...) is allowed - ping between each netns are failing - tests between ns1 as a receiver and ns>1 are failing - other tests not involving ns1 as a receiver are failing So not only for the loopback test. Now a clearer message, including the time it took to run all tests, is displayed.

2021-06-18selftests: mptcp: enable checksum in mptcp_join.shGeliang Tang
This patch added a new argument "-C" for the mptcp_join.sh script to set the sysctl checksum_enabled to 1 in ns1 and ns2 to enable the data checksum. In chk_join_nr, check the counter of the mib for the data checksum. Also added a new argument "-S" for the mptcp_join.sh script to start the test cases that verify the checksum handshake: * Sender and listener both have checksums off * Sender and listener both have checksums on * Sender checksums off, listener checksums on * Sender checksums on, listener checksums off The output looks like this: 01 checksum test 0 0 sum[ ok ] - csum [ ok ] 02 checksum test 1 1 sum[ ok ] - csum [ ok ] 03 checksum test 0 1 sum[ ok ] - csum [ ok ] 04 checksum test 1 0 sum[ ok ] - csum [ ok ] 05 no JOIN syn[ ok ] - synack[ ok ] - ack[ ok ] sum[ ok ] - csum [ ok ] 06 single subflow, limited by client syn[ ok ] - synack[ ok ] - ack[ ok ] sum[ ok ] - csum [ ok ] Acked-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Geliang Tang <geliangtang@gmail.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

2021-06-16selftests: net: veth: make test compatible with dashAndrea Righi

Moreover, in case of missing bpf object, the script is exiting -1, that is an illegal number for dash: exit: Illegal number: -1 Change the script to be compatible both with bash and dash and prevent the errors above.

2021-06-14ipv4: Fix device used for dst_alloc with local routesDavid Ahern
Oliver reported a use case where deleting a VRF device can hang waiting for the refcnt to drop to 0. The root cause is that the dst is allocated against the VRF device but cached on the loopback device. The use case (added to the selftests) has an implicit VRF crossing due to the ordering of the FIB rules (lookup local is before the l3mdev rule, but the problem occurs even if the FIB rules are re-ordered with local after l3mdev because the VRF table does not have a default route to terminate the lookup). The end result is is that the FIB lookup returns the loopback device as the nexthop, but the ingress device is in a VRF. The mismatch causes the dst alloc against the VRF device but then cached on the loopback. The fix is to bring the trick used for IPv6 (see ip6_rt_get_dev_rcu): pick the dst alloc device based the fib lookup result but with checks that the result has a nexthop device (e.g., not an unreachable or prohibit entry).
